General Information
| Biological Significance | The D-EA p138 is an antigen codified by the gene BALF2 which is the major DNA binding protein of EBV. At the time of infection with Epstein-Barr virus, antibodies to EA are found and usually last for four to six months only. The absence of antibody to EA when other EBV antibodies are present strongly suggests that first time infection with EBV occurred in the past. |
